📌 3 Key Takeaways

🎯
Objective & Hypothesis:By doping ZrO2 to the SiO2 with aerogel; the Co(II) and Se(VI) from metal and glass industry wastewaters can be removed due their large surface area and high pore volume.
📊
Key Findings & Data:For maximum Se(VI) and Co(II) adsorptions (99% and 96%) the optimum Nano-SiO2 / ZrO2-Calcium Alginate Aerogel composite concentrations was found as 4 mg/l, at a pH of 6.0 at a temperature of 80 0C after 45 min contact time.
💡

Abstract

By doping ZrO2 to the SiO2 with aerogel; the Co(II) and Se(VI) from metal and glass industry wastewaters can be removed due their large surface area and high pore volume. For maximum Se(VI) and Co(II) adsorptions (99% and 96%) the optimum Nano-SiO2 / ZrO2-Calcium Alginate Aerogel composite concentrations was found as 4 mg/l, at a pH of 6.0 at a temperature of 80 0C after 45 min contact time. Nano-SiO2 / ZrO2-Calcium Alginate Aerogel were reused with the percentages of 83 % and 87% for Co(II) and Se(VI), respectively after four sequential utilisation. This reduce the treatment cost by 38%.
